In the LPM case, if the tx desc has been force
freed in the dp_bus_suspend ->dp_find_missing_tx_comp,
then after data transfer resumed, fw may report
tx complete for the same tx desc, and we should
skip it to avoid null pointer access.
The reason why set default vdev_id to 0xff is:
Since in this case, it happned disconnect before
suspend, so the tx desc pool will be deleted and
reinitalized when resume, so the pdev is null in
the force freed tx_desc and vdev_id should be changed
from 0 to DP_INVALID_VDEV_ID, otherwise the below logic
in the tx complete handler will not skip handling
this freed tx_desc.
if (qdf_unlikely((tx_desc->vdev_id == DP_INVALID_VDEV_ID) &&
!tx_desc->flags)) {
DP_STATS_INC(soc, tx.tx_comp_exception,1);
dp_tx_desc_check_corruption(tx_desc);
continue;
}

WCN6450 is a chip based on Rhine architecture. Unlike LI/BE targets,
chipsets based on Rhine (RH) do not have host facing UMAC HW blocks.
Their corresponding SRNG interfaces are also removed. The functionality
of these UMAC HW blocks is replaced with a software implementation in
the firmware. Communication between the driver and firmware will happen
over copy engine (CE).
Although there are no host facing UMAC HW blocks, the CE hardware used
in WCN6450 expects the host driver to use the TX descriptor (HW) format
of LI targets during TX packet enqueue. Therefore it is required to
create a new pool of TX descriptors (HW) pool for WCN6450 that is used
during TX.
The logic to create/free/init/deinit these descriptors is specific
to WCN6450/Rhine, therefore it is implemented in architecture specific
Rhine code.
Introduce new APIs in struct dp_arch_ops {} to allocate and free
arch specific TX descriptors. These ops will be no-op for LI/BE
architectures.
Also for Rhine targets, allocate/free other TX descriptors like TX EXT &
TSO descriptors as part of the arch APIs.

The kernel-doc script identified a large number of documentation
issues in dp/wifi3.0/li, so fix those issues. In addition, there are a
number of instances where public functions have their implementation
documented instead of having their interface documented, so move that
documentation.

Currently HTT_TX_FW2WBM_TX_STATUS_DROP and HTT_TX_FW2WBM_TX_STATUS_TTL
are mapped to HAL_TX_TQM_RR_REM_CMD_REM which results in the wrong Tx
status print in case HTT_TX_FW2WBM_TX_STATUS_TTL where No ack is received.
So to fix the status log issue map HTT_TX_FW2WBM_TX_STATUS_DROP to
HAL_TX_TQM_RR_REM_CMD_REM and HTT_TX_FW2WBM_TX_STATUS_TTL to
HAL_TX_TQM_RR_REM_CMD_TX to log correct Tx Fail Status.

When TX completion is released from FW, dp_tx_notify_completion()
will not be invoked, then TX DCHP ACK will miss
hdd_softap_notify_tx_compl_cbk() which then
WMI_PEER_CRIT_PROTO_HINT_ENABLED with value 0 will not send to FW.
(1) move dp_tx_notify_completion() from dp_tx_comp_process_desc_list()
to dp_tx_comp_process_tx_status(), so that both TX completion release
source FW or TQM case will call it.
(2) clear TX notify flag for intra-bss forwarding BC/MC to avoid
unnecessary TX completion notify.
(3) Set ts.status for release source FW case otherwise it will be value
0 always.

Tx descriptor is not being freed and put back in tx desc
pool for a long time. As a result, system is not going
into suspended state.
To find this descriptor, during dp_bus_suspend and
dp_runtime_suspend, parse through the descriptor pool to
check for any descriptors not freed for a long and trigger
self recovery when found.

Currently, to set checksum enable flags in Tx descriptor
we are checking the csum_enabled flag along with stack checksum
offload request. In case of roaming from latency-critical connection
to non-latency critical connection we request stack to calculate
checksum and set csum_enabled flag to 0. For some packets which
are already queued where the stack has not calculated checksum and
csum_enabled flag is set to 0, we will not set the checksum enable
flags in Tx descriptors for those packets.
To fix the issue remove the csum_enabled flag check and directly
check if the stack has calculated checksum for those packets or not.
